A total of 226 swordfish samples collected from Taiwanese fishing vessels in the Indian and Atlantic oceans were examined for total mercury (THg) and organic Hg (OHg). Analysis of 56 pooled white muscle samples showed that THg and OHg concentrations ranged from 0.056 to 3.97 (1.3 +/- 0.97) and from 0.043 to 3.92 (1.01 +/- 0.82) microg g(-1) flesh mass, respectively. These values were similar to those from various previous studies during the past three decades. THg and OHg were significantly linearly correlated with fork length (FL, cm) of the fish from Indian and Atlantic oceans; however, there was no significant OHg%-FL relationship. OHg and THg also were significantly correlated. Fishes with FL < or = 140 cm met the methyl Hg (meHg) regulatory standard set by the European Commission Decision (meHg < or = 1.0); and fish with FL < or = 211 cm met the Taiwanese Food and Hygiene Standard (meHg < or = 2.0). Weekly swordfish consumption rates and amounts are recommended accordingly.
对从印度洋和大西洋的台湾渔船采集的226份箭鱼样本进行了总汞（THg）和有机汞（OHg）检测。对56份合并的白色肌肉样本分析显示，THg和OHg浓度分别为0.056至3.97（1.3±0.97）和0.043至3.92（1.01±0.82）微克/克鱼肉质量。这些值与过去三十年中各项先前研究的值相似。THg和OHg与来自印度洋和大西洋的箭鱼叉长（FL，厘米）显著线性相关；然而，OHg%-FL之间没有显著关系。OHg和THg也显著相关。叉长≤140厘米的箭鱼符合欧盟委员会决定设定的甲基汞（meHg）监管标准（meHg≤1.0）；叉长≤211厘米的箭鱼符合台湾食品卫生标准（meHg≤2.0）。据此建议了每周箭鱼的食用率和食用量。
